Mendes, the striker's agent, has been actively sounding out potential suitors for the past four weeks - and he's landed several high-profile bites:

MONACOWas Leonardo Jardim protecting a club asset? Or was he rolling out the welcome mat? The AS Monaco coach was adamant this week that Falcao would "come back to the levels he was at in the past". The Portuguese is understood to be drawing up contingency plans in the event Falcao does, indeed, return from Manchester United this summer. Encouraged by their run to the Champions League quarterfinals, ASM owner Dmitry Rybolovlev, while scaling back their spending, also would be happy to go again with Falcao next season. The relationship between Monaco management and Falcao's agent, Jorge Mendes, remains watertight and the prospect of resuming his career in the Principality would be seriously considered by the Colombian.

JUVENTUSBeppe Marotta, the Juve GM, must be fed-up competing with United for strikers. After wining and dining Robin van Persie's agent, Kees Vos, for several weeks, Marotta was convinced they had the former Arsenal striker - only for United to swoop in at the final moment. And then last summer, by his own admission, Marotta was convinced of a deal for Falcao - until United stepped in and sealed an agreement in the final hours of the transfer window. In his two weeks of interaction with Monaco during their Champions League quarterfinal, the prospect of ferrying Falcao to Turin was again raised by Marotta. Other ASM players were discussed, but the chance of finally landing the Colombian was seriously explored. He has played down the prospect this week, citing Falcao's huge personal demands. But intermediaries insist this is just a bit of kideology. An outline of a deal is on the table - another 12 month loan, with Juve and ASM sharing Falcao's salary and the Bianconeri having the option to make the transfer permanent in June 2016.

RIVER PLATEIt's a long shot for River, but they've thrown their hat into the ring this month. Word reached River's board that Falcao's agent, Jorge Mendes, had begun sounding out interested clubs about the Colombian and they moved quickly to make their interest public three weeks ago. Matias Patanian, River's vice-president, was given the brief to put in the call to their former star. On local radio, Patanian made it clear "the doors are open" to Falcao. Whether it's this summer or in the January transfer window, River are ready to welcome him home.

VALENCIALos Che are an intriguing option for Falcao. Peter Lim, Valencia's new owner, is a Manchester United fan and actually co-owns Salford City along with United coach Ryan Giggs. Valencia also enjoy a close relationship with Falcao's agent, Jorge Mendes, boasting the likes of Andre Gomes and Joao Cancelo on their books. There's also coach Nuno, who worked so successfully with Falcao when in charge of Porto. With Alvaro Negredo set to be returned to Manchester City at season's end, Valencia will be in the market for a new centre-forward and the idea of Falcao leading the line would be attractive to Lim and the club's marketing team.

LIVERPOOLAlong with Chelsea, Jorge Mendes has been in touch with Liverpool to gauge their interest in Falcao. After the problems with Mario Balotelli, would Brendan Rodgers have the bottle to gamble again on Falcao? But it's a different risk with the Colombian. No-one at Carrington questions Falcao's attitude. Indeed, it's quite the opposite. It's his application on the training pitch that has most impressed United staff. If he can assure Rodgers of his long-term fitness, we could see a rare transfer from United to Liverpool take place this summer. Like Juve, Liverpool were well down the line in talks for the Colombian before United's late intervention last summer.
